Species I have grown.
This image was taken in Cumbria and is of the fertile hybrid between M. betonicifolia and M. grandis. It is called Lingholm after a garden in Cumbria where it first occurred many years ago. If you want to grow big blue poppies then this is the only one you need grow. Masses of seed about which germinates well - even some commercial seed houses offer it (though such seed is often a year older than from seed exchanges). Currently trying to learn how to use this blog - hence the number of posts!
